Two kilometres underground near Sudbury, Ont. , a machine has reached a temperature so low it barely seems real.

A new study suggests that failing to detect dark matter signals in some galaxies may not contradict evidence seen in our own.

Dark matter has been thought to be cold and collisionless, meaning its particles don't interact with each other. The new study, however, challenges this assumption.

The difference is like a crowd of people who ignore each other versus one where everyone is constantly bumping into one another,’ says scientist ...

Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

Somewhere in the distant universe, light from a quasar bends around a galaxy and reveals a dark clump so compact it should ...

A study led by UC Riverside physicist Hai-Bo Yu suggests that a new type of dark matter could explain three astrophysical ...

Joseph Shavit The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal ...

Deep beneath the Earth’s surface, a major physics experiment has reached a critical milestone, enabling detectors to operate at temperatures near absolute zero.

Learn how a two-state model of dark matter could explain why gamma-ray signals appear in some galaxies but not others.

The SuperCDMS is chilled to right around absolute zero, and its detectors are primed to hunt dark matter particles.

Scientists are aiming to redefine how we search for dark matter. A new theoretical ...
